To all whom t may concern;

Improvements in Glass-Melting Furnaces, of

which the following is a specification. My invention relates to a glass-melting furnace, Iand more vparticularly to a regenerative tankfurnace for the continuous melting ofglass. To this end the present invention consists in a new and improved vglass-melting furnace',

.l in the novel features of construction, and in the combination of parts, all as afterdescribed and claimed. .A In the accompanying drawings,'whichillusmelting-chamber; 4

,partment The' yserrlicirc nlar 'wall 'offA the` other compartment or chamber 7 is formed with W'o'rkmg-ot holes 9, asfis usual in .tankfurnaces ofthisclass. g Idesire to call? particular attention f to the location of and'to the means for introducingthe chagesto Athe tureI of thepresentfinventionis a checker- Work bathe-wall:10J- This vwall, as shown by the drawings,'is upon thefbridge-wall 5,

and preferably -4 extends upwardly .l to within a short distance of theroof of the furnace.

'AMsL'EIa a citizen of the'United States, residing at'Pitts-1 I burg, lin the county of Allegheny and State'of Pennsylvania, have invented new and useul namely, in themelting-compartment.

from the respective4 pairs 4of regeneratora `unite tofform a ythroat cir-passage 14, which throat; or' passage communicatesI with an throats or. passages 14' have been.sup orteil' upon or' by vthe `rear walliof the tan and when it becomes -necessary, to `repair or .re-

place the saidrear wall, as isfrequen-tly the case :in the operation of glass-melting-fur- 'vfnaces ofthis c laSS, the said throats or pas- '.sages andthe ,rear wall loflthe furnace, which designates a passage through'thebridgef wall connecting-compartments 6 and? 'and gas'passages I2 and 13, leading-to and 'may not .and usually donot need repairing,

have hadto be partially or wholly torn down i and rebuilt. Infmy construction-the throats or'passa es are supported by means entirely lindepen ent'of the tank or its rear wall, and

consequently the wearing away.ordestruc' 'tion or' sald 4wall and its subsequent 'repair-or repla'cementd'oes not aectthe throats or '1'passages, nor the rear wall ol' the furnace.

The 'means `for supporting the respective ,tliroats or passagesand the rear Wall of the furnace,'as illustrated and as preferredhcom- ,prise a steel framing comprising two suithaving y'a' ,bracket 18" secured thereto,- cross-beams 19v beams 21.
